IP Prefixes: 81.0.0.0/8
Whisper Internet Directory lists every BGP-announced IP prefix whose first octet is 81, covering the 81.0.0.0/8 address space. Prefixes are ordered lexically by their CIDR string; each one links to its canonical page at /prefix/<cidr> showing the announcing ASN, sample IPs, and any active MOAS conflicts.
